To say that I love my 300 f/2.8L IS would be a major understatement. If it was not for my wife, I think I might actually sleep with this lens.

I wouldn't, it's a bit hard when you roll over . Nioce shots, were those shots with a monopod or handheld? I find it's ok for short periods handheld, but it is on the heavy side when you can't put it down for a rest every now and again. Mine usually has a 1.4x extender attached for wildlife.

Thanks. These were shot hand held. I find moving around the track with a monopod or tripod too restricting.

The Black-crowned Night Heron (Nycticorax nycticorax) commonly abbreviated to just Night Heron in Eurasia, is a medium-sized heron found throughout a large part of the world, except in the coldest regions and Australasia (where replaced by the closely related Rufous Night Heron, with which it has hybridized in the area of contact).

Adults are approximately 64 cm long and weigh 800 g. They have a black crown and back with the remainder of the body white or grey, red eyes, and short yellow legs. Young birds are brown, flecked with white and grey. These are short-necked and stout herons.
